Abstract: Natural resource investigation and monitoring is an important measure to adapt to the needs of ecological civilization construction in the new era. By making full use of hyperspectral remote sensing and information technology means. Take Qinzhou, Beihai and Fangchenggang in Guangxi as an example, research on the application of high-score hyperspectroscopic remote sensing technology in natural resource monitoring. Master the basic conditions of the type, area, scope, distribution, ecological function and changes of natural resources, Form a set of feasible natural resource monitoring process based on high-score hyperspectral remote sensing technology. To provide timely, accurate and stable basic geographic information services for core businesses such as dynamic monitoring, early warning, assessment and management of natural resources, ecological and environment, It provides data foundation and technical support for the construction of ecological civilization, the protection and restoration of mountains, rivers, forests, fields, lakes and grass, and natural resources management.

自然资源主要包括土地、矿产、森林、草原、水、湿地、海域海岛等天然存在、自然形成的资源,涵盖陆地和海洋、地上和地下。如何对这些资源进行监管,是承载着生态文明建设和自然资源综合管理的关键[1]。

利用高分高光谱遥感技术开展自然资源调查与监测,查清我国各类自然资源家底和变化情况,为科学编制国土空间规划,逐步实现山水林田湖草的整体保护、系统修复和综合治理,保障国家生态安全提供基础支撑,为实现国家治理体系和治理能力现代化提供服务保障。[2]

高分高光谱遥感技术,是利用狭窄连续的光谱波段对地物持续遥感,获取丰富的空……
